Teddington KBB Fire Valve 90° 6m 1/4" - 356460

The KBB is a fast acting thermally operated valve with a spring loaded trip mechanism and sealed temperature sensing system consisting of a bellows, capillary tube and sensor phial. The valve will snap closed when the temperature at the sensor phial exceeds the set value. The valve will remain in the shut-off condition until the appropriate action has been taken to restore normal operating conditions and the reset button has been pressed. The operation of the fire valve can be verified by using the KBT1000 test unit set to the appropriate temperature. This checks that the operation to shut-off the oil supply pipe takes place and enables a check to be made that the valve can be manually reset once the sensor phial temperature has reduced to normal operating level. The reset button must be pressed firmly to ensure the valve is positively latched in the open position. The valve can also be shut-off manually by pulling the reset button.
